[PATCH 2/2] drm/fb-helper: Move drm_fb_helper_force_kernel_mode() inside #ifdef

From: Geert Uytterhoeven
Date: Tue Aug 04 2015 - 09:22:25 EST


From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

If CONFIG_MAGIC_SYSRQ is not set:

drivers/gpu/drm/drm_fb_helper.c:390:13: warning: 'drm_fb_helper_force_kernel_mode' defined but not used [-Wunused-function]
static bool drm_fb_helper_force_kernel_mode(void)
^

Move drm_fb_helper_force_kernel_mode() inside the existing #ifdef to fix
this.
